Another very important objectof the in ventionv lies in the provision `of a structure of s this 'nature which includes a pair of trans Figure 1 is a top plan view of the hayv sweep embodying the features of my invention y j` Fig. 2 is an enlarged detailylongitudinal section taken substantially on lthe line 2-2 .of Fig. l,

Fig. 8 is an enlargeddetail transverse sec-V tion through the sweep taken substantially on the line 3 3 of Fig. 9, y Fig. 4 is a detail perspective view showing the forward end of one of the teeth, Y

VFig. 5 is an enlarged fragmentary elevation showing a modification of oneY of the cross supports. f

Referring to the drawing in detail it will `V`be' seen that the numerals 5 and 6 denote 'I cross supports which are disposed in spaced parallelism. The cross support 6 has wheels 7 journaled thereon in any suitable or preferred manner., These wheels 7 are preferably disposed equidistant 'from each end thereof. Numerals 8 denote draft tongues orrods which are pivotally engaged at theiry forward ends as at9 inbrackets 10 mounted on the rear cross support 5. These tongues or rods 8 may be'attached to draft means such as a tractor or Yanyother suitable means ink any preferred manner so that the sweep may be pushed ahead of the draft means used. I

A plurality of castings A and B are mounted respectively on cross supports 5 and 6. Each casting A, B is U-shaped in formation to include a bight 11 disposed under the 2s, 1926. I serial No.'` 157,518.

cross,support,5, 6 andk avpair of upstanding s .legs}12, the Vupper .extremities of. whichy are K' bifurcated as is illustratedin Figurek 2h The `bights Hare-provided with longitudinally 11A-ofthe casingsrA are providedV with forare provided with horizontal ears 16. A bolt A,17 isslidable through theV ears 1G andan tension 15. Teeth 18 extend through the openings 14 and the bolts 17 engage in openings therein being held normally engaged by springs 19 impinging vagainst theshoulders 2() and ears 16. The teeth 18 are T-shaped in cross section as is illustrated in Figure 3 but the forward ends thereof are tapered to form noses 21 as isillustrated to advantage in Fig. 4. VMembers 22 are formed in the shape of an isosceles triangle but have corners pivoted f as at 23 in the bifurcated extremities of the extending VT-shaped openings 14. Thebights ward extensions 1,5 and thev forward legs lv :opening` in the topof the correspondinge'xy legs 12 and other corners thereof are provided with ears 24 through which pass bolts 25. Thus two of the members 22 are associated with eachcasting A, B, and the bolt 25 may be adjusted for swinging these members 22 so as to clamp the castings A, B,-

upon the cross support 5, 6. In Figure 5 it will be seen that the cross supports may be circular if so desired'fas is indicated at 6.

yIt is thought that the construction, utility Vand advantages of thisfdevice will Vnow be apparent to those skilled' in this art without a more detailed description thereof. present embodiment of kthe invention has been disclosed in detail merely by way of example since in actual practice it attains Athe features of advantage enumerated as desirable inthe statement ofthe invention and the above description. It is apparent that changes. in the details of construction, and

The..

in theV combination and arrangementk of parts may be resortedto without departing fromV the spirit'or scope ofthe invention as hereinafter claime advantages. Y s Y HavingL thus described my inventionwhat I claim as new is: s 1'. lA hay sweep comprising a pair of cross isupports disposed in spaced parallel relation, a plurality'of U-shaped members having their bight'portions positioned under the d or sacrificing any of itsv -supports and their legs rising upwardly, Y

means engaged'with the extremities of said legs to clamp the members 'onthe supports7 said bight portions having longitudinal;-

.1 l movement.

ly extending openings, teeth `extending through the openings in spaced parallelism, and means on some ot the members for engaging the teeth to lock them against longitudinal n'iovement in the openings.

2. A hay sweep comprising a pair of cross supports disposed in spaced parallelism7 a )lurality of U-shaped members havingtheir liiglit portions positioned under the supports and their legs rising upwardly7 `pivoted members on the upper extremities ot the legs, bolts engaging said piroted members to clamp the U-shaped members on the supports, said bgllt portions having longi tudinally extending openings, teeth extenfb ing through the openings 1n spaced parallelism with each other, andmeans on some ot the `U-sliapcd members for engagingithe teeth to lock them against longitudinal 3. A hay sweep comprising a pair of cross supports disposed 1n spaced parallel relation, a plurality et U-shaped members `having their bight portions positioned under` these supports and their legs rising upwardly, triangular members having corners pivoted on the upper extremities of the legs, ears projecting from other corners of the tri` angular members, bolts passing through the ears so that the U-shaped members may be clamped on the supports, said bight portions being provided with longitudinally extend ing openings, teeth extending through the openings in spaced parallelism and means 0n some of the members for engaging the teeth to lock movement.

In testimony whereof ture.
